i too have been looking for transdermal you can easily obtain it in the form of androgel but in my opinion DHT is better; known as andractim it is roughtly 30times more potent than androgel and can help with gyno and local muscle growth also it doesnt convert to estrogen unlike any testosterone which is a plus, simply search andractim you will find your source.
